About Us

In 1990, friends Todd Johnston and Keith Laine established Johnston Electric Sign Company with a C-45 license, $100.00 and a ladder. Within a few short years due to their shared knowledge, skill and experience the company flourished. Keith left the business to
pursue other interests in 1994 and Todd Johnston continued to build upon their shared vision for the company. Johnston Signs now occupies a state of the art facility located in Sebastopol, Sonoma County CA., easily accessible to the other 8 San Francisco Bay Area Counties.

We are dedicated to providing our clients with high quality signage, and customer satisfaction is very important to us. Every job, big or small, is handled with personal attention and with your business in mind. We strive to go above and beyond in order to meet every client's needs and to exceed their expectations, regardless of the size of the project. We stand behind our promises to produce high-quality products that last, and most importantly, to make things easy for you. Our goal is to help our clients get the most from their budget.

Our reputation has been built on excellent product quality, safe and reliable installations, and friendly service. We manufacture, service and install all types of signs.
